Title: Vacuum brazing method for aluminum
Inventor: HAKOZAKI MASATOSHI
IPC: B23K1/00
Filed: 1986-06-25
Abstract: PURPOSE:To improve the reaction to the oxidation prevention of a brazing part by Mg and to reduce the contamination inside a furnace by optically shielding the respective body to be treated by storing it inside the box body having the gap communicating to the inside and outside in case of brazing inside a vacuum brazing furnace. CONSTITUTION:The upper cover 11 of the box body 10 composed of the upper cover 11 and bottom plate 12 made of the thin sheet of a stainless steel, etc. is of the rectangular parallelopiped box body opening to the lower part and the size of the inner part is set slightly larger than the body W to be treated whose external appearance is of rectangular parallelopiped. On the other hand the bottom plate 12 has the frame 12a whose peripheral edge part is bent in the prescribed length. The body W to be treated is placed on the bottom plate 12 and the upper cover 11 is covered. In this case the lower edge part of the upper cover 11 is overlapped at a slight interval 13 with the frame 12a and the state of a gap 14 existing between the upper cover 11 lower edge and bottom plate 12 becomes. This box body 10 is placed on a carrier frame, the whole body is charged into a vacuum brazing furnace 1 and the brazing is performed with the filler metal containing the Mg of a reducer. In this way the Mg molecule density around the body to be treated can be made higher and the sprash of Mg into the furnace can be reduced.

IPC: H02M7/497
Filed: 1994-06-30
Abstract: PURPOSE:To eliminate an abnormal current and eliminate the restriction on a switching pattern against the changeover of a carrier frequency by a method wherein, when switching patterns of respective inverters are zero-vectors, their carrier frequencies are successively changed if the operation frequencies of the inverters are in a high speed range. CONSTITUTION:An operation frequency fo is compared with a set frequency fL in S1 and, if the operation frequency is in a low frequency range, when the changeover of a carrier frequency is required in S2, carrier frequencies of all the inverters are changed simultaneously in S3. On the other hand, if the operation frequency exceeds the low frequency range, the times of interruptions from a reference PWM inverter is fixed and phase errors between the reference inverter and other inverters are eliminated in S4 and, if the changeover of the carrier frequency is required in S5, the carrier frequency of the reference inverter is changed in S6. Then the carrier frequencies of the second and thereafter inverters are successively changed when the switching patterns of the respective inverters are zero-vectors in S7-S8.

Title: Optical system for light scanning
Inventor: KANEKO YUTAKA
IPC: G02B26/10
Filed: 1981-09-24
Abstract: PURPOSE:To decrease the pitch of scanning lines by using trapezoidal prism for an optical light-scanning system used for an optical recording device like a laser printer. CONSTITUTION:Piece of laser luminous flux L1, L2, and L3 emitted at some angles of spreading from plural semiconductor laser output parts 2 are passed through two sperical lenses 3 and 4 to obtain parallel pieces of laser luminous flux while principal beams of laser luminous flux are also made parallel. Those  pieces of laser luminous flux are passed through two cylindrical lenses 6 and 7  and a trapezoidal prism 5 and reflected by a deflector constituted as a rotary  polygon mirror 8 to illuminate a scanning surface, i.e. the surface of a photosensitive drum 10 through an imaging lens 9. Thus, beam spots S1, S2, and S3 of  the respective pieces of laser luminous flux are imaged on the drum surface. In  this case, when the prism is arranged slanting (rotating) around an imaginary  line 19 at an angle eta to a plane 17, those beam sports S1, S2, and S3 slant at an  angle 2theta, so the pitch P2 of scanning lines becomes less than that during incidence. Therefore, the pitch of the pieces of laser luminous flux, i.e. the pitch  of scanning lines is reduced without slanting an output part in an y-axis direction.

Title: Semiconductor device
Inventor: YAMADA TAKAHIRO
IPC: H01L29/80
Filed: 1985-07-08
Abstract: PURPOSE:To obtain the saturation current characteristic by removing the influence of drain upon a potential barrier layer by the introduction of a shielding region. CONSTITUTION:A shielding gate region 105 is the region that shields electrostatically the potential fluctuation of N<+> region 104 of drain from being transmitted to an intrinsic gate region 111. If a channel width WG2 determined by the shielding gate region 105 is maintained along a distance LG2 and a depth DG2, the electrostatic shielding conditions become as LG2>WG2>TK-DG2 and the shielding gate region 105 is used in an inverse bias state to N<+> region 104 of drain under the condition of DC and it and it is grounded under the condition of AC. Thus, the potential fluctuation of the N<+> region 104 of drain is completely shielded from reaching a potential barrier layer of the intrinsic gate region 111.

Title: Data transfer method
Inventor: ASHIZAWA YUJI
IPC: G06F12/08
Filed: 1986-06-27
Abstract: PURPOSE:To transfer data at a high speed and with high efficiency by informing a CPU board having no cache memory form another CPU board having a cache memory that the cache memory is not used. CONSTITUTION:When a CPU 15 transfers data to a CPU 10, the CPU 15 stores the data in a shared memory 16 and informs the end of preparation to the CPU 10 for transfer of data to start a program which controls the discontinuation or the actuation of a cache memory 11. Thus the CPU 10 confirms an interruption to stop the actuation of the memory 11 and fetches the data A from the memory 16. Then the memory 11 is set again after the data A is fetched so that the memory 11 is actuated. A C.CPU board 9 and a subsidiary memory 13 are controlled by the board 9 and therefore no interruption is applied to a reading action carried out from the memory 13 of the CPU 10.

Title: Fixing device and image forming paper therefor
Inventor: NUMAZU TOSHIHIKO
IPC: G03G15/20
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce paper jamming when paper enters a thermal fixing roller mechanism. SOLUTION: The paper on which an unfixed toner image is transferred is carried by a carrying device, the carried paper is received by the thermal fixing roller mechanism 57 and the paper is held between a heating roller 60 and a pressure roller 61 of the thermal fixing roller mechanism 57 and is carried thereby while imparting heat and pressure to the paper. At that time, a mold- releasing oil is applied on a peripheral surface of the heating roller 60 by an oil applying roller 58. In this fixing device 33, a paper entering roller mechanism 59, which is composed of right and left two sets of entering roller members 70 which carry the paper by holding both end parts of the paper therebetween, is disposed in the vicinity of the thermal fixing roller mechanism 57 at its upstream side.  Thereby when the paper enters the thermal fixing roller mechanism 57, right and left two sets of entering roller members 70 hold both end parts of the paper therebetween and compulsorily carry the paper. Accordingly the paper can surely enter between the heating roller 60 and the pressure roller 61 of the thermal fixing roller mechanism 57 and thereby paper jamming can be prevented.
